Different SSH key for different client user accounts
I have a droplet. And I am using CentOS Web Panel Pro edition also.
I was able to create and use SSH key for root user to login through SSH.
But how can I create and allow others users that I created to access SSH using keys.
Suppose I created a new user "jack". Now how can I give make it access SSH using Key.
I created a .ssh folder inside "/home/jack/.ssh" and copied the "authorized_key" file. I updated the public key in this file from the one I generated using puTTy for this new user.
Now when I try to access the SSH using the corresponding private key, I get an error message in SSH console as below:
Using username "jack".
Server refused our key
Can someone help me in this?
